The samples were obtained from artisanal fishing with gillnets, from June 2014 - July 2015. The individuals were measured, weighed and dissected to remove the stomachs. The fish diet was analyzed using the methods: Gravimetric, Frequency of Occurrence, Dominance of the item and Food Index.

Layman Marine Sciences Program Department of Biological Sciences Florida International University 3000 NE 151st Street North Miami, FL 33181 Phone: 786-390-0578 Email: [email protected] Abstract In estuarine ecosystems, maintaining the proper balance of freshwater and marine inputs is essential for proper ecosystem function, and anthropogenic alterations of this balance (namely, freshwater flows into estuaries) are of particular concern to resource managers. Differences in freshwater flows and associated salinity patterns can influence biodiversity or the relative abundance of organisms. Freshwater flows are especially important to small tributaries that transverse the margin between uplands and estuaries and are important habitats for many young- of-the-year marine finfish and shellfish. Little is known, however, about the effects of these habitat alterations on trophic ecology of coastal fishes. We used stomach contents and stable isotope analysis (δ13C, δ15N) to examine the effects of freshwater flow alterations on the trophic ecology of juvenile common snook (Centropomus undecimalis) in four mangrove creeks with different freshwater flow regimes: two creeks considered ‘less degraded’ (their drainages are largely intact) and two creeks are ‘more degraded’ (drainages have been altered by development and drainage ditches).

Av. Dom Manuel de Medeiros, s/n, Departamento de Pesca e Aquicultura, Dois Irmãos, Recife, PE, Brasil. CEP: 52171-900. Corresponding author: [email protected] Abstract: This study provides information on the feeding habitats of Centropomus undecimalis and Centropomus parallelus in two estuaries of Pernambuco, Northeast Brazil. Specimens were collected every three months from February 2013 to June 2014 in the estuary of Sirinhaém River (south coast) and the Estuarine Complex of Santa Cruz Channel (north coast). To access diet composition we used frequency of occurrence %Fo; numerical frequency %N and weight percentage %W. Multivariate analysis of MDS, ANOSIM and SIMPER were used to evaluate the similarity and differences of the diet between species and regions. A total of 390 individuals were evaluated. The results indicate that the Estuary of Sirinhaém River and the Estuarine Complex of Santa Cruz Channel are used as a feeding ground by the Centropomus species. The diet of the C. undecimalis and C.parallelus in both areas was based primarily on Crustaceans - Decapoda and teleosts. C. undecimalis appeared as a predator with piscivorous tendency in the two study regions, whereas C. parallelus was classified as zoobentivorous in the south coast and as piscivorous in the north coast.

Abstract: Common snook Centropomus unidecimalis is an important commercial and fishery species in Southern Mexico, however the high exploitation rates have resulted in a strong reduction of its abundances. Since, the information about its population structure is scarce, the objective of the present research was to determine and compare the age structure in four important fishery sites. For this, age and growth of common snook were determined from specimens collected monthly, from July 2006 to March 2008, from two coastal (Barra Bosque and Barra San Pedro) and two riverine (San Pedro and Tres Brazos) commercial fishery sites in Tabasco, Mexico. Age was determined using sectioned saggitae otoliths and data analyzed by von Bertalanffy and Levenberg-Marquardt among others.

Nine species of metazoan parasites were collected: 1 digenean, 1 monogenean, 1 acantocephalan, 1 nematode, 4 copepods, and 1 isopod, and 96.2% of the fishes were parasitized by one or more metazoan, with mean of 85.3 ± 122.9 parasite/fish. The digenean Acanthocollaritrema umbilicatum Travassos, Freitas & Bührnheim represented the majority of the parasites specimens collected, totaling, 94.7%. This species was the most abundant, prevalent, and dominant, showing positive correlation with the host's total body length and parasite abundance. The copepod species Acantholochus unisagittatus Tavares & Luque presented differences in abun- dance in relation to sex of host. The mean diversity in the infracommunities of C. undecimalis was H = 0.095 ± 0.116, with no correlation with the host's total body length but correlated with the host's sex.

División Académica de Ciencias Biológicas, Universidad Juárez Autónoma de Tabasco, 967 Villahermosa, Tabasco, México; [email protected] Received 23-IV-2010. Corrected 08-X-2010. Accepted 08-XI-2010. Abstract: In Southeastern Mexico, Centropomus undecimalis is an important fish species of sport and commer- cial fisheries for coastal and riverine communities. Fisheries along rivers and coasts depend on migratory habits of this species, and these movements are probably related to reproduction. In spite of its economic importance, few studies have been conducted focusing on its reproductive biology, and this research aims to analyze these habits. Samples (fork length, somatic and gonads weight, and macroscopic maturity stages) were obtained from organisms collected by fishermen from the largest fishing cooperatives along the coastal and riverine areas of Tabasco, from July 2006 to March 2008. Fish size ranged from 34 to 112cm fork length, with an average age of 6.42 years for males and 9.12 years for females. In riverine areas, fish sizes ranged from 30 to 85cm and the average age was 5.5 years for males and 6.6 years for females.
